Bulk Glutamine Peptides are a peptide bonded form of the conditionally essential amino acid, Glutamine. Conditionally essential means that in certain situations, levels of Glutamine are depleted at a faster rate than the body can re-synthesise them. One example is strenuous exercise, which results in depleted levels of Glutamine in muscle tissue. Due to the peptide bonded structure of Glutamine Peptides, the product is more stable which is advantageous when adding Glutamine to other products, such as protein shakes. Glutamine Peptides are also stable at higher temperatures when compared to L-Glutamine.
